	~~MK1-250 heads from the 2015 onward should have platinum RTD wires~~, ~~and therefore use the firmware labeled "FILAMENTS_33A.hex" or "hothead.mk400.33A.hex" (these are actually the same file with different names).~~		With version 4 and above, all heads take the same firmware!

	~~MK1-250~~ heads ~~from 2014 and earlier should have red RTD wires, and therefore use the firmware labeled "OLD_NOJUMPERS_232A.hex" or "hothead_232A.hex" (these are also~~ the same ~~file with different names).~~

	~~Very old MK1-250 heads may have a wire jumper (usually red or yellow), as shown. These boards use the~~ firmware ~~labeled "OLD_JUMPERS_232J.hex" or "hothead_jmpr_232J.hex".~~
